Additional Details:

The S10K350 has a varistor voltage of 350V. Refer to the datasheet for specific details on surge current capability, clamping voltage, and energy handling capability. It's generally a leaded disc varistor designed for through-hole mounting. Dimensions and lead configuration can be found in the datasheet.

Varistors are non-linear resistors whose resistance decreases significantly when the voltage across them exceeds a specific threshold. This characteristic allows them to divert excess current away from sensitive components, providing effective surge protection. The S10K350 is designed for repetitive surges, offering reliable overvoltage protection in numerous electronic applications.
